Installation Notes

1. Mounting: Install on 35 mm DIN‑rail; ensure 50 mm clearance around the switch for airflow and cable management.
2. Power Connection: Connect dual 24 V DC power inputs to redundant power supplies; verify correct polarity to avoid component damage.
3. Port Configuration: Use copper ports for local IONet devices; connect fiber ports for long‑distance links (max 2 km).
4. Cabling: Use CAT5e/CAT6 cables for copper ports (max 100 m); use multimode fiber (OM1/OM2) for fiber ports (LC‑type connectors).
5. LED Verification: Confirm Power A/B, Link/Activity, and Fault LEDs are active after installation; troubleshoot link loss or speed mismatch using per‑port LEDs.
6. Environmental Protection: Install in an IP54‑rated enclosure to complement conformal coating and protect against dust, moisture, and chemical exposure.
